空中花园黑鸟, an annex of the Air Force Flight Test (AFFT) Museum at Edwards AFB, was officially dedicated on September 27, 1991. It is the world’s only display of a Lockheed SR-71A together with its predecessor A-12, along with the once ultra-secret D-21 drone and the only remaining U-2 “D” model in the world.

空中花园的设立是为了保护家庭黑鸟军用飞机的光荣传统。
